Description
TECHNICAL FIELD
The invention of the present application relates generally to the
field of coin wrappers. More particularly, this invention relates
to a coin wrapper comprising a flexible paper substrate and a
pressure-sensitive adhesive which contacts the coins.
BACKGROUND OF THE INVENTION
Various types of coin wrappers are well known in the art and have
been used for many years to facilitate the handling and storage of
coins. Typically, such wrappers are made of a flexible substrate
which encloses a stacked roll of coins all having the same
valuation. The coin wrappers are typically designed to accomodate a
convenient unit of value, for example $5 or $25 worth of coins.
A useful coin wrapper must be flexible enough to conform to the
diameter of a roll of coins. It must be strong enough to maintain
the coins in a stacked roll without splitting, tearing, or
otherwise releasing the coins when repeatedly and sometimes roughly
handled. However, the useful coin wrapper must also quickly and
easily release the coins when needed. It is also desirable that a
coin wrapper be adapted for machine rolling of coins, to eliminate
the need for tedious hand rolling.
Coin wrappers are used in volume by almost all places of trade
handling cash. Financial institutions utilize an enormous quantity
of coin wrappers. They are also routinely used by restaurants,
service stations, stores, and the like, where it is common to see
an employee unwrapping a roll of coins to provide additional change
for the cash register.
A variety of coin wrappers have been used in the past or are
currenty in use. Paper tubes are very common. Typically, the paper
tubes are folded or crimped over the ends of the coin roll to hold
the coins in place. Various means are used to remove the coins from
such a wrapper. Generally, when the wrapper has folded ends, the
ends must be unfolded and the roll manipulated or shaken to
dislodge the coins. Removing coins in this way can be time
consuming.
Where the ends are crimped, frequently a pull tab is provided
somewhere along the length of the wrapper, which when pulled will
tear the wrapper away from the coins. However, this has proven
unsatisfactory because in many cases the paper does not tear
uniformly but instead shreds or breaks off, making the unrolling
process more difficult. It also happens that sometimes during
handling of the coin rolls, inadvertently the tab is pulled causing
the wrapper to tear and coins to spill out. To prevent this,
instead of a tab some coin wrappers provide a cut-out or recessed
area along a diagonal or lengthwise seam, so that a person can
start tearing the wrapper at that point. However, it is generally
quite difficult to begin tearing the paper from a cut out area in
the absence of long fingernails or other suitable implement.
Further, the problems of uneven tearing and shredding still
occur.
Another commonly used coin wrapper is a paper wrapper designed to
split open when the roll is rapped sharply against a hard surface.
Generally the employee or clerk wll strike this wrapper against the
cash register to open it. However, the registers in use today are
frequently electronic digital instruments having circuitry and a
memory system which easily can be damaged by a jolt or strike.
Consequently, it is highly undesirable that coin rolls be struck
against these registers, and in fact some institutions have posted
notices to this effect on their registers.
A more recent development is the clear plastic tube sealed around a
roll of coins. This wrapper is known as a "fry tube". It is
believed that this wrapper is heat-shrunk around the roll to
maintain the coins in the stacked position. It has proven very
difficult to remove the coins from the fry tube wrapper. It is not
uncommon for the operator of a cash register to have a razor blade
on hand to slit open the fry tubes. The presence and use of a razor
blade presents obvious dangers and use of the blade can be overly
time consuming when customers are waiting.
Thus, substantial need exists for a coin wrapper which will quickly
and easily release the coins without cutting, striking, or awkward
tearing.
SUMMARY OF THE INVENTION
The present invention is a wrapper for a roll of coins. The wrapper
is a flexible substrate having a length and a width. The width of
the substrate is greater than the circumference of the coins in the
roll, and the length of the substrate is greater than the length of
the coin roll. Along its length, which is the direction
corresponding to the length of the coin roll, the substrate has as
general areas an inside edge and an outside edge. The inside edge
is as a general area that length edge closest to the coins when
wrapped. At the opposite end of the substrate is the outside edge,
which is visible on the outer surface of the wrapper wrapped around
a roll of coins.
The substrate also has an inner and an outer surface. The inner
surface faces radially toward the coin roll when the roll is
wrapped. The outer surface faces radially away from the roll when
wrapped.
On the inner surface of the substrate is a coin-supporting amount
of an effective clean-releasing pressure-sensitive adhesive in an
appropriate configuration.
Specific advantages of the invention will become apparent with
reference to the accompanying drawings, detailed description of the
invention, and claims.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of a preferred embodiment of the coin
wrapper of this invention.
FIG. 2 is a perspective view of a preferred embodiment of a roll of
the coin wrappers as shown in FIG. 1.
FIG. 3 is a perspective view of a second preferred embodiment of a
roll of the coin wrappers as shown in FIG. 1.
DETAILED DESCRIPTION OF THE INVENTION
Referring now to the Drawings, wherein like reference numerals
denote like elements throughout the several views, FIG. 1
illustrates a coin wrapper 10, rolled about a stack or roll of
coins 12. The roll of coins 12 has a length 14, which will depend
upon the thickness of each coin in the roll and the total number of
coins, and a circumference 16, which is the distance around the
coins.
Coin wrapper 10 comprises a flexible substrate or sheet 18. For
simple reasons of economy, and for its interaction with the
adhesive later described, the substrate is preferably paper.
Substrate 18 includes a length 20 and a width 22. The length 20 of
substrate 18 is greater than or equal to length 14 of coin roll 12.
Length 20 of the substrate can be significantly greater than the
length of coin roll 12, for example, to provide a 1.3 centimeter or
more overlap on each side of the coin roll. However, it is
preferable that length 20 be no more than approximately 2
millimeters greater than the length of coin roll 12. In the context
of this invention, this slight overlap is sufficient to maintain
the coins in the roll. Length 20 can also provide substantially no
overlap whatsoever, being substantially the same length as the
length of the coin roll.
Width 22 of the substrate is at least slightly greater than
circumference 16 of the coin roll. Preferably width 22 is
approximately twice the circumference, and more preferably, for
reasons of a more sturdy wrapped coin roll, approximately at least
three times the circumference 16 of the roll.
Side edges 36 and 38 are those substantially parallel edges which
are closest the ends of the coin roll when wrapped.
The substrate also includes an inside edge 24 and on outside edge
26, both along its length. Inside edge 24 contacts the length of
the coin roll when the roll is wrapped, and is typically covered by
an overlapping portion of the substrate and thus is not visible
when the roll is wrapped.
Outside edge 26 is located at the opposite end of the substrate
from inside edge 24. As seen in FIG. 1, outside edge 26 is visible
when the roll is wrapped.
Outside edge 26 can include a tab portion 28. Preferably, tab
portion 28 is V-shaped, coming to a point near the center of the
roll. Tab portion 28 provides for greater ease in unwinding the
coin roll when it is desired to release the coins.
Substrate 18 further includes an inner surface 30 and outer surface
32. Inner surface 30 faces radially toward the roll when wrapped.
It is a portion of this surface which is in contact with
substantially the entire length and circumference of the coin roll
when wrapped. Outer surface 32 generally does not contact the
coins, but instead faces radially away from the coins when the roll
is wrapped.
Located on inner surface 30 is a coin-supporting amount of an
effective pressure-sensitive adhesive 34. Adhesive 34 is located
along inside surface 30 in any configuration which will maintain
the coins in the desired stack or roll. Effective configurations
are illustrated in FIGS. 2 and 3.
In FIG. 2, the adhesive is located along edges 36 and 38 and along
the inner surface of outside edge 26. There is a break in the
adhesive along outside edge 26, at point 40 of tab portion 28. The
adhesive along outside edge 26 generally contacts the coin wrapper
itself rather than contacting the coins. It serves to maintain the
wrapper in the rolled position.
FIG. 3 illustrates a preferred adhesive configuration. The adhesive
is applied in a series of broken strips. This configuration
generally provides sufficient adhesion such that the coin wrapper
will remain wrapped but easily can be unwrapped when desired.
The suitable pressure-sensitive adhesives useful in this invention
are those which have sufficient adhesion to maintain the coin
wrapper in the roller position, but which readily and cleanly
release from the coins as the wrapper is removed. The adhesives
useful in the context of this invention will leave no discernable
trace on the coins, so that the coins will have no sticky or tacky
feel. The preferred pressure-sensitive adhesive for use in this
invention is an isooctylacrylate homopolymer adhesive cast on a
paper substrate at a low coating weight.
One combination of adhesive paper substrate useful in this
invention is that combination found in the 3M brand "POST-IT".sup.R
notes.
It is envisioned that a release paper backing could be used over
the adhesive if necessary, to be removed prior to use of the
wrapper. However, for reasons of economy and simplicity, it is
preferred that the adhesive be one which does not require use of a
release paper backing.
A wrapped roll of coins can be formed according to this invention
by arranging coins in a roll formation having a length 14 and two
opposite circular sides 44 and 46 having circumference 16. This
coin roll is contacted along its length with the inside edge 24 of
the substrate 18. Preferably this is accomplished by simply placing
the coin roll along or near edge 24 in a position substantially
parallel to length 20 of the substrate and substantially
perpendicular to edges 36 and 38. It is preferable that at least a
portion of length 14 contact at least a portion of the
pressure-sensitive adhesive 34. Preferably, as seen in FIG. 3, the
roll will be placed along a strip of adhesive. By placing the roll
on a strip of adhesive, the coins are held in place to facilitate
wrapping the coin roll. Once the coin roll has been placed on the
wrapper, the roll is then rolled or wrapped to form a cylindrical
wrapped coin roll as shown in FIG. 1. If desired, and if there is
sufficient overlap, edges 36 and 38 can be folded over circular
sides 44 and 46.
To release the coins from the roll, one merely lifts tab portion 28
at point 40 and pulls to unwrap the coins. If desired, and if the
adhesive allows, the same coin wrapper can be used again one or
more times.
It is envisioned that the coin wrappers of this invention can be
made available in the form of a large roll 48. Roll 48 comprises at
least two or a series of coin wrappers 10 divided or separated by
perforations 50. The perforations can delineate a tab portion 28.
Such a roll of coin wrappers would be highly useful in financial
institutions and other businesses utilizing large numbers of coin
wrappers. It would be highly convenient for personnel to merely
tear off a wrapper when needed.
Roll 48 could be manufactured by methods known in the art such as
where a sheet of paper would be printed with the adhesive pattern
and any perforations would be added. It is also envisioned that
roll 48 comprising the wrapper of this invention would facilitate
machine wrapping of coin rolls.
Further, it is envisioned that the coin wrappers of this invention
could be available in tablet or pad form.
Obviously many modifications and variations of the present
invention are possible in light of the above teachings. It is
therefore to be understood that, within the scope of the appended
claims, the invention may be practiced otherwise than as
specifically described.
